The Stacked View Extension is a ThunderBird add-on that adds a thread panel to the left side of the email client. This feature arranges email messages in a stacked view, making it easier to navigate and manage email threads.
To activate this feature, simply select the menu item View > Layout > Stacked View. It's that easy!
One key requirement to keep in mind is that Thunderbird 1.0 or later is needed for this layout to work properly. However, if you meet this requirement, the stacked folder/thread layout can be a truly helpful addition to your email management routine.
